This just means people are using ArcGIS to manage data, which they shouldn't be doing.

Is there a way to do this in raster calculator? Would Int( Floor( [in_raster] + 0.5 ) ) suffice? Or even Int( [in_raster] + 0.5 ) ?

Thanks a lot Neil! I will try this. Only thing is, the pit bases are not flat. So the depth from the known elevation of the start of the slope at the top will vary around the pit. We did already discuss a similar idea to yours though so thanks a lot. And thanks for the negative buffering tip. Essentially what I'm thinking of doing is iterating through a number of buffer distances then running the slope classification tool on the resulting TIN to see whether (most of) it is less than 30 degrees. It's a fun little problem to play around with and will be interesting to see the result. You should also see the response from whuber here. Wil

This is a cut/fill problem. We have pits that have been dug in the ground, usually rectangular. They have a bund wall around them. They are being rehabilitated by pushing the bund back into the pit. Usually the bund is not enough to refill the pit. We need to achieve a maximum 30 degree slope between the original land surface outside the feature and the backfilled material pushed in from the bund. We need to know if we have enough material in the bunds to achieve this angle of slope. We know the bund volume from topographic survey (interpolated the original land surface under the bund from elevation points outside the feature in the topographic data). From this interpolated surface we know the location and height from which the 30 degree slope will start and go down into the pit. Is there a tool in any GIS or CAD program that will take this line (as a polyline or polygon for example), take the angle (in this case 30 degrees) and output a new line or polygon showing where the topographic surface will be intersected, right the way around the pit? With this new line, a TIN could be created of the elevations along it at the bottom of the proposed slope and the elevations of the intersection at the top of the slope between the original land surface and the topographic surface. The topographic surface could then be subtracted from this new TIN to get the volume and see whether it is the same or less than the volume in the bund. If there is a tool to automate this, it would make life much easier. Otherwise we could calculate a few points around the pit manually for a coarser estimate.

Hi Willy, Agreed, it looks like there is plenty of control over leader lines although unfortunately not over their anchor points as far as I can tell. ArcMap thinks it can only choose between the right vertical centre or the left vertical centre of the bounding box (presumably) of the text. It does not get to choose also between the top or bottom horizontal centre. This can make for awkward leader lines as I have shown in the second image above. Converting to annotation does not provide extra anchor points. None of the leader line editor options provide extra anchor points. The only way to overcome it so far as I can see is to remove the leader line and using the Drawing toolbar to add one using, effectively, a different anchor point. This is what I did to produce the line in the second image. It's a really simple issue and I'm only raising it because it seems so straightforward and it's surprising it was overlooked. If they do choose to fix it, why not allow for 8 anchor points at corners and centres of the bounding box edges? Wil

In the attached image you can see that leader lines have 2 possible anchor points, the vertical centre of the left and right of the text bounding box. Unfortunately, it is not possible for the anchor point to be the horizontal centre of the top or bottom of the bounding box. Try it yourself by dragging the end of a leader line in a circle around the text it will snap between the left and right only. This makes for awkwardly placed leader lines in cramped conditions. For example, if the text is directly above the item to which the leader line is pointing, it will have to go at an angle down from the vertical centre of the text across to a point below the horizontal centre, see next image. In the above image you can see the results of my suggestion (a line I have had to draw in using the Draw toolbar) where the line has an anchor point at the horizontal centre of the top of the text bounding box. Can ESRI add one at the top and the bottom to accompany the ones on the left and right? Microsoft Word and Excel have something like this functionality when you insert a shape: Their leader line version, however, is a line where you can adjust the position of the anchor and the destination point. This might be optimal for ArcMap too. Thanks, Wil

Oh, it's easy. just select from map layers list the ones you want as candidates for the legend. send all of these across to the legend items list. click the 'only display layers that are checked...' box. voi la

I have created an ArcReader map for staff which has a number of imagery layers, such as satellite imagery and a raster topographic map. I also have a legend which automatically updates based on which layers are selected in the table of contents. How do I exclude the imagery layers, though, because they are not useful in a legend? When they appear in a legend they are just RGB colours.

Wilfred, Have you tried accessing one of your images by just typing in the address in a browser. Your problem sounds like the path to the image is not correct or you do not have access to the image. Regards Anthony Hi Anthony, Thanks for your interest. I checked this by clicking the frame with the broken link symbol. It then showed the path that it was trying to retrieve the image from. I found that it was pointing to the wrong folder on the web server. I simply transferred the photos to the folder it was in fact pointing to, and voi la, the photos now come up in the pop up. I then commented out the following: <name>offices</name> <fields>  and it still works. I'll put this down to being confused as I'm new to developing Flex apps. Wil

Hi all, I am using the identify widget v 3.0.1. I have successfully set it up to identify a point dataset, displaying some items only in the pop up. I now want to display photos in the pop up. It does not, however, display such images even when I have, to my knowledge, been setting up the config file correctly (see below). Any help much appreciated. Yes, the map service is set up with a field called 'photo' containing the file name and extension of the photos so it matches up with the prefix in the syntax of the identify widget below. I checked that this field is accessible to the widget by adding it into the list to be displayed when one uses the widget (see bolded syntax below). Strangely, this then caused the pop up to behave as though it were displaying the photos, but only a frame with a broken image symbol in the middle appeared. Also, the red x image in the identify tool results was also replaced with a broken image symbol. <?xml version="1.0" ?> <configuration> <betareturngeometryfix>false</betareturngeometryfix> <identifylayeroption>visible</identifylayeroption> <identifytolerance>5</identifytolerance> <defaultzoomscale>5000</defaultzoomscale> <keepidentifyactive>true</keepidentifyactive> <returngeometryforzoom>true</returngeometryforzoom> <enablelineselect>true</enablelineselect> <enableextentselect>true</enableextentselect> <enablepolyselect>true</enablepolyselect> <enablemouseovergraphicsinfo>true</enablemouseovergraphicsinfo> <enablemouseoverrecordinfo>false</enablemouseoverrecordinfo> <usemaptime>false</usemaptime> <infoautoclosemilliseconds>2000</infoautoclosemilliseconds> <autoactivatedtool>mappoint</autoactivatedtool> <excludebasemaps>true</excludebasemaps> <disablepopuplinks>false</disablepopuplinks> <labels> <zoom2message>Click to Zoom to Point</zoom2message> <identifylabel>Identify</identifylabel> <resultslabel>Results</resultslabel> <descriptionlabel>Use the identify tool to identify features on the map:</descriptionlabel> <pointlabel>Identify by Point</pointlabel> <linelabel>Identify by Polyline</linelabel> <rectlabel>Identify by Rectangle</rectlabel> <polylabel>Identify by Polygon</polylabel> <clearlabel>Clear</clearlabel> <loadinglabel>Loading...</loadinglabel> <removeresultmessage>Remove Result</removeresultmessage> <idfrom>Identify From</idfrom> <noresultsfoundlabel>No Results Found</noresultsfoundlabel> <resultsfoundlabel>Results Found</resultsfoundlabel> </labels> <useproxy>  </useproxy> <layers onlythese="true"> <layer> <name>offices</name> <fields> <field name="photo" alias="photo" /> <field name="Address" alias="Address" /> <field name="City" alias="City" popuponly="true"/> <field name="State" alias="State" popuponly="true"/> <field name="Postcode" alias="Postcode"/> </fields> <links> <link includeinresults="true" field="photo" alias="photo" tooltip="hi this is a tooltip"> <linkprefix>https://example.example.com/example/example/example/Documents/photos/test</linkprefix> <linksuffix></linksuffix> <iconfield></iconfield> <iconprefix>https://example.example.com/example/example/example/assets/images/edit_markertool.png</iconprefix> <iconsuffix></iconsuffix> </link> </links> <zoomscale>15000</zoomscale> <forcescale>true</forcescale> </layer> <layer> <name>QLD rail</name> <fields> <field name="FNAME" alias="Name" /> <field name="WIDTH" alias="Gauge" popuponly="true"/> <field name="ELECTRIFIE" alias="Electrified?" popuponly="true"/> <field name="OP_STATUS" alias="Status"/> <field name="ESRIdate" alias="Date"/>popuponly="true" dateformat="YYYY/MM/DD"/> </fields> <links> <link includeinresults="false" field="" alias="" tooltip=""> <linkprefix></linkprefix> <linksuffix></linksuffix> <iconfield></iconfield> <iconprefix></iconprefix> <iconsuffix></iconsuffix> </link> </links> <zoomscale>15000</zoomscale> <forcescale>true</forcescale> </layer> </layers> <symbols> <simplefillsymbol color="0x448ccb" alpha="0.4" style="solid"> <outline color="0x448ccb" alpha="0.8" width="2"/> </simplefillsymbol> <simplemarkersymbol style="circle" size="12" color="0x448ccb" alpha="0.8" xoffset="0" yoffset="0" angle="0"> <outline style="solid" color="0xffffff" alpha="0.8" width="1"/> </simplemarkersymbol> <picturemarkersymbol url="assets/images/i_info.png" height="30" width="30" xoffset="0" yoffset="0" /> <simplelinesymbol color="0x448ccb" alpha="0.8" width="2"/> </symbols> </configuration>

Hi Robert, I am getting a 1085 error when using the Identify 3.01 tool. I followed your PDF help file in constructing the <layers> portion of the syntax, the rest of the syntax remains unchanged from the tool as I downloaded it. Yes, the REST service name is what is used for the <name> tag. Here is my syntax: <layers onlythese="true"> Hi Rober, thanks for your prompt reply. This problem has been fixed simply by deleting the widget folder and starting again from scratch. You're right, probably was a syntax error elsewhere. I note, however, that using <fields all="true"> appears not to display all fields. I appreciate your above comment that it is better to display only relevant fields, although it would be good to know why the tag doesn't seem to work, only displaying the layer name but no field values. <?xml version="1.0" ?> <configuration> <betareturngeometryfix>false</betareturngeometryfix> <identifylayeroption>visible</identifylayeroption> <identifytolerance>5</identifytolerance> <defaultzoomscale>5000</defaultzoomscale> <keepidentifyactive>true</keepidentifyactive> <returngeometryforzoom>true</returngeometryforzoom> <enablelineselect>true</enablelineselect> <enableextentselect>true</enableextentselect> <enablepolyselect>true</enablepolyselect> <enablemouseovergraphicsinfo>true</enablemouseovergraphicsinfo> <enablemouseoverrecordinfo>false</enablemouseoverrecordinfo> <usemaptime>false</usemaptime> <infoautoclosemilliseconds>2000</infoautoclosemilliseconds> <autoactivatedtool>mappoint</autoactivatedtool> <excludebasemaps>true</excludebasemaps> <disablepopuplinks>false</disablepopuplinks> <labels> <zoom2message>Click to Zoom to Point</zoom2message> <identifylabel>Identify</identifylabel> <resultslabel>Results</resultslabel> <descriptionlabel>Use the identify tool to identify features on the map:</descriptionlabel> <pointlabel>Identify by Point</pointlabel> <linelabel>Identify by Polyline</linelabel> <rectlabel>Identify by Rectangle</rectlabel> <polylabel>Identify by Polygon</polylabel> <clearlabel>Clear</clearlabel> <loadinglabel>Loading...</loadinglabel> <removeresultmessage>Remove Result</removeresultmessage> <idfrom>Identify From</idfrom> <noresultsfoundlabel>No Results Found</noresultsfoundlabel> <resultsfoundlabel>Results Found</resultsfoundlabel> </labels> <useproxy>  </useproxy> <layers onlythese="true"> <layer> <name>offices</name> <fields all="true">  </fields> <links> <link includeinresults="false" field="" alias="" tooltip=""> <linkprefix></linkprefix> <linksuffix></linksuffix> <iconfield></iconfield> <iconprefix></iconprefix> <iconsuffix></iconsuffix> </link> </links> <zoomscale>15000</zoomscale> <forcescale>true</forcescale> </layer> <layer> <name>QLD rail</name> <fields all="true">  </fields> <links> <link includeinresults="false" field="" alias="" tooltip=""> <linkprefix></linkprefix> <linksuffix></linksuffix> <iconfield></iconfield> <iconprefix></iconprefix> <iconsuffix></iconsuffix> </link> </links> <zoomscale>15000</zoomscale> <forcescale>true</forcescale> </layer> </layers> <symbols> <simplefillsymbol color="0x448ccb" alpha="0.4" style="solid"> <outline color="0x448ccb" alpha="0.8" width="2"/> </simplefillsymbol> <simplemarkersymbol style="circle" size="12" color="0x448ccb" alpha="0.8" xoffset="0" yoffset="0" angle="0"> <outline style="solid" color="0xffffff" alpha="0.8" width="1"/> </simplemarkersymbol> <picturemarkersymbol url="assets/images/i_info.png" height="30" width="30" xoffset="0" yoffset="0" /> <simplelinesymbol color="0x448ccb" alpha="0.8" width="2"/> </symbols> </configuration> DATES I have another question about the documentation. You say to consult the ESRI date format documentation, which I found here. It appears to say that a date should be in "yyyy-mm-dd". The date in my map service, however is YYYYMMDD. I created a new date field, threw the YYYYMMDD data in there but it uses / instead of -. As you can see in the syntax for the second layer in the identify tool, I tried to get it to display the dates in YYYY/MM/DD format, since in the map service they are in DD/MM/YYYY. What is the problem with the date? EDIT: also, I forgot to mention that the date should only show in the pop up, but in fact it shows in the list of results as well, not only the pop up. Thanks so much for making this tool. Wil

It partially supports Khmer unicode presently, although there are unnecessary spaces between the characters for some reason. More information: http://gis.stackexchange.com/questions/21636/khmer-unicode-script-in-arcgis-10 Remove the tendancy to put in the spaces, and it's fixed.

I have a field containing alphanumeric values in the following format: A-AA00 Sometimes they are also A-AAA0 I need a python script I can put in the field calculator in ArcMap 10 that will at least remove the numeric characters, and retrain the alphabetical ones and the hyphen. So that, for example, this: A-AA0 becomes this: A-AA I also want to replace the numeric chars with numeric chars from another field. This Stack Exchange entry addresses this issue, but the string has a space before the number and this can be used for splitting and indexing... my strings are not so handily constructed.

fixed by converting in the map and setting the annotation group reference scale to zero in the data frame properties.
